Having a proper path to success will lead to you getting into what you want to do when you are older. Always plan your homework and never let yourself get behind, study even if it seems unnecessary. To be the person who knows everything will become an advantage in life because employers will actually hire you. The business people like to hire those who know a lot. It allows you to pick out bad decisions from the good without doubt.
Next, another advantage of preparing early for those college years is that you will know what area suits you best. You do not want to be the person working a job you thought you would like. Only to learn that the job makes your life absolutely miserable. Figure out what areas you excel in and find out what you might like the most. The last thing you want to do is be doing the thing you dislike with all your passion. Be prepared to go through many difficult times where you cannot find the perfect career, that will happen. Just keep going because everyone ends up finding their dream
